While you are making an origami crane, you will learn two bases: (1) square base and (2) bird base. For many people, origami crane might be the first model to learn origami folding. So it is like a prerequisite for more advance models.

This origami crane is different from the traditional origami crane. It is based on calyx base instead of bird base. It is a bit skinnier than the traditional one.

This traditional origami crane II also starts from bird base. The special feature of this model is an unique shape of two wings.

This flying origami crane is derived from bird base. You will learn both inside reverse-fold and outside reverse-fold from this model. One special folding technique that you will learn from this flying crane is asymmetric squash-fold.

This flying origami crane II starts from a bird base. Two special folding techniques involved with this model are open sink-fold and inside reverse-fold.
